PCT No. PCT/SE95/00229 Sec. 371 Date Nov. 12, 1996 Sec. 102(e) Date Nov. 12, 1996 PCT Filed Mar. 3, 1995 PCT Pub. No. WO95/23884 PCT Pub. Date Sep. 8, 1995EMI shielding materials in form of plates, panels, and fabrics and methods for their preparation and for preparing highly filled ferromagnetic fibers therefore are described. In the method the ferromagnetic filler is treated in an ultrasonic dispenser or a ball mill in the presence of a binder polymer and then the fiber is made by wet spinning from a dispersion containing solution or gel of the polymer.
